How to Extend the Windows 7 RC Activation Trial Period Up to 120 Days
1. Open the Start Menu.

2. In the Start Menu search box, type regedit, and press Enter. (See screenshot below)

3. In the registry, go to: (See screenshot below)
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform

4. In the right pane, see if SkipRearm is set to 0 (number 0) . (See screenshot above)
A) If it is not set to 0 - Right click on SkipRearm and click on Modify. Type 0 and click on OK. (See screenshot below)

B) If it is set to 0 - Skip this and go to step 5.
5. Close regedit.

6. Open a elevated command prompt.

7. In the elevated command prompt, type slmgr -rearm and press Enter. (See screenshot below)

8. Click on OK. (See screenshot below)

If you get one of these errors below, then do what is above the error:
  • You will need to restart the computer first, then repeat steps 6 to 8 again.

  • You have used up your 3 times. You will need to activate or reinstall Windows 7.

9. Close the elevated command prompt. (See screenshot below step 7)

10. Restart the computer to apply the changes and reset your trial period back to 30 days to activate.

This is really old news.
It's been more than 120 days since the RC version was available ... And there's a newer version anyway.
It's time to purchase a legal version now ... Even though it doesn't run as fast as the RC version

There's been an update .. And I'm not sure re-arming will work now anyway.
Need More Input
